This invention relates to safety pins. An object of this invention is to provid in a safety pin means for locking the pin. element in and constructed that when the pin element. is normally engaged with the keeper, the pin element willnot be locked, but when the back bar of the device is bent or bowed inwardly the point of thepin will be shifted endwise. to a position confronting the lockingmeans, and release of the bowed back will result in the point of. the pin element moving endwise into the locking means therelfor, sothat the pinelement will be locked against normal pressur tending to release the same from the keeper.

To the foregoing objects and others which may hereinafter appear the invention consists of the novel construction, combination and'arrangement of parts as. will'fbemore specifically referred to and illustrated in the accompanying drawing, wherein are shown embodiments, but it is to be understood that changes, modifications and variations maybe resorted to which fall within the scope of the invention as claimed. 7

In the drawings:

Figure'l is a detail'sid'e elevation of a safety pin constructed according to an-embodiment of this invention, I

Figure 2 is a view similar to Figure 1, but showing the device'with the pin released from the locking means embodied in the keeper,

Figure 3 is a fragmentary plan view of the device,

Figure 4 is a sectional view taken on the line 4-4 of Figure 3, v

Figure 5 is a sectional view taken on the line 5-5 of Figure 1,

Figure 6 is a fragmentary plan view of a modified form of this invention,

Figure 7 is a fragmentary sectional view taken on the line 1-1 of Figure 6,

Figure 8 is a fragmentary side elevation partly in section of another modification of this invention,

Figure 9 is a fragmentary plan view of another modification of this invention.

Figure 10 is a sectional view taken on the line Ill-l0 of Figure 9,

Figure 11 is a fragmentary top plan of a further modification, and

Figure 12 is a sectional view taken on the line I'Il'l of Figure 16.

Referring to the drawings, the numeral l0 designates an elongated resilient back bar and the numeral ll designates generallya pin which is integral with the back bar l0, being-connected" therewith by means of a coil Hi. The freeend' of the back bar I0 is grippedor otherwise firmly secured to a keeper, generally designated as l2.

The keeper I2 includes a, U-shaped keeper' member M which is spaced from the back bar Ill and extends inwardly in. the. direction of'the point l5 of the pin member H. The: keeper" [2. includes a centrally disposed divider 16 which ex tends from the rear portion ll of th keeper'andl is positionedbetween the opposite. sides of the. U-shaped keeper membe [4. The keeper member at, a. point outwardly from the. inner end thereof is formed with ani'nwardly ofiset. detent l8' which opens inwardlyrthe bight IQ of. the

keepermember l4 being cut, as indicated at, 2.0,

so" that the detent lB-will open orface inwardlyin order that the terminal end of the point l5- may be .positionedon the outerside of the. detent I8 being; extended through the opening 20 as shown in Figure 4.

In order to. provide for the extension of the point l5 into the locking member or detent. IE,

it. isv necessary, as shown in- Figure 2, to bend or bow the back bar l0 inwardly with the pin H1 engaged withinthe keeper'member l4: With the point [5 bearing against the inner side. of. the

bight I8 of the keeper'member l4 and the back bar lll bowed inwardly, the terminal end of'the point I5 will be positioned inwardly from the inner edge of the detent or looking member l8, as shown in Figure 2.

The back bar l0 may be released then and the return of the back bar II! to its normal configuration, which is the configuration shown in Figure 1, will provide for the endwise movement of the pin I l outwardly until the point. l5 engages within the concave outer side of the detent or looking member l8. In this position which is the position shown in Figure 4, the pin H is locked against inward movement by the detent or locking member I8 and is locked against outward movement by the bight {9 of the keeper member ll.

Referring now to Figures 6 and '7, there is disclosed a keeper member 2| which is identical with the keeper member I2. In this modified form of the invention, the keeper element 22 has struck inwardly from the bight thereof an inwardly bowed or bent strip 23 constituting the locking member. The strip or looking member 23 is struck inwardly by cutting the bight of the keeper element 22, as indicated by the numerals 24 and 2s.

23 in the same manner as the engagement of j' pin II with looking member or detent 18, that is,

by bowing of the back bar inwardly so as to move the pin 26 endwise until the point thereof is positioned inwardly of the inner edge of the inward- V V 7 4 r 7 tion of U-shaped cross section having side arms 1y offset locking member 23. t

' Referring to Figure 8, the numeral 28 designates generally a keeper structure with which a pin 29 is adapted toQb'e engaged. 'The keeper structure 28'is U-I-sh aped in transverse section and the bight Bil-of the keeper has a lug 3| struck inwardly therefrom with the lug 3| provided with an opening 32. The point of the pin 29 is adapted to'engage within the opening 32 as shown in FigureB.

' Referring now to Figures 9 and 10, the numeral 33 designates generally a" U'-shaped,keeper with which a pin 34 is adapted to be engaged. The keeper 33' has struck, from the bight 35 thereof ber 36 is struck from one side of the'bight 35 and is then bent inwardly and provided with a concave outer side 31 forming'aseat for the pin 34.

1 Referring now to Figures 11- and 12, there is-disclosed a further modified form of keeper and locking means for the pin. In this form the keeper 58 has struck inwardly from the bight 59 thereof a pinlocking member 60. The pinlock-a ing member 60 extends lengthwise of'thea'djacent side' of the keeper Bil -having its free end 6| innermost and the opposite sides BZof the lock-' ing members cut away from theadjacent portions of the bight 59. The outer side-of the lock-.

ing member iifiis concave, "as shown in Figure 12, so as to providea seat with'which the pointof the pin 63 may be engaged.

' In the pin lockingstructuresshown in Figures 9 andll', the free edge or edges of theflocking members 36 and 60, respectively,zare spaced from the adjacent portionof the keepers Hand 58,

'a pinlocking member'36. ,This' pin locking mem-J bending of said bar. V

2. A safety pin as set forth in claim 1 wherein a free inner end.

respectively, a distance sufficient so that the pins 34 and 63 may be inserted in the locking mem- -bers from the side or sides of the locking mem- V bers without banding or distortion of the pin, or with only slight distortion of the latter. These pin locking constructions therefore provide a second means whereby the point of the pin may be inserted in the locking, member.

In the constructions shown in Figures 9 and 11 adjacent ends of said bar and said pin, a U- shaped keeper fixed to said bar at the end thereof opposite from'said coil and having a terminal porand a bight, the bight and side arms of said keeper embracing said pin and a pin locking member between said arms overlying the point of said pin whereby the point of said pinean onlyibe released from said locking member by endwise movement of said pin eifecte'd by longitudinal said locking member inter-connects said arms.

3. Asafety pin as set forth in'claim 1 wherein said locking member is elongated and is formedwith parallelfree' opposite longitudinaledges and 4. A safety pin as set forth in claim 1 wherein said locking member is integralat one lengthwise edge with said keeper.
